Product Overview
The ABB 69037615F BGDR-01C is a specialized drive-internal brake chopper and gate driver control module engineered for ABB’s ACS800, ACS850, and ACS880 family frequency converters. Within ABB’s spare-parts nomenclature, the “BGDR” designation identifies a brake-related component in the drive’s DC-bus management chain, specifically the control/interface PCB that monitors DC-link voltage and fires the braking IGBT/chopper to route regenerated energy into an external brake resistor . The ABB 69037615F BGDR-01C also functions as an IGBT gate driver board, converting low-voltage PWM logic signals from the drive controller into the high-voltage gate drive pulses required to switch the power semiconductors, while providing critical electrical isolation between the control and power circuits .
The ABB 69037615F BGDR-01C serves as a critical protective interface within the drive’s power architecture. When a connected motor regenerates energy during fast deceleration, overhauling loads, or downhill conveyor operation, the drive’s DC-link voltage rises. The ABB 69037615F BGDR-01C continuously tracks this bus voltage and, once the threshold is reached, switches the braking IGBT on/off in PWM fashion to clamp the bus via an external DCR-type brake resistor . Without a functioning brake chopper path, DC-bus voltage climbs until the drive trips on overvoltage, or worse, the DC-link capacitors are stressed beyond design limits.
As a mature, field-proven component within ABB’s extensive drive spare-parts portfolio, the ABB 69037615F BGDR-01C remains actively deployed in the substantial installed base of ACS800, ACS850, and ACS880 drives across cranes, hoists, conveyors, marine winches, and high-inertia test benches worldwide. The module is also referenced by the alternative part number 3AUA0000074145 in ABB’s documentation and ordering systems .
